Seamlessly connected living and dining spaces are designed for effortless entertaining, with expansive glass sliders that invite natural light and open to the outdoor living areas. A double sided gas fireplace anchors the main living space and extends into a sophisticated lounge with a built-in bar. A first floor junior primary suite provides ideal guest accommodations with its own private bath. Beautifully detailed main and back staircases lead to all three levels. The second floor includes the primary suite- a true retreat; stunning sunsets and golf course views, a private balcony, fireplace, dual walk-in closets, with french doors and a center island, a spa inspired bath with a double vanity, soaking tub, large format slab shower, and water closet. There are four additional en-suite bedrooms, including one with a private balcony and a charming bunk room with it's own sitting area. A large laundry room with dual washers and dryers complete this level.
